Abstract

In the proposed approach, an Extended Model Predictive Sliding Mode Controller (EMPSMC) is
designed to control Three-Level Ac/Dc Power Converters to achieve improved dynamic performance
and better. Steady-state stability. The traditional proportional-integral (PI) controller is used in the
Model Predictive PI controller (MPPIC) technique to produce active power reference. However, this
technique results in a significant overshoot/undershoot and steady-state error. Instead of PI, sliding mode control (SMC) is used to overcome these shortcomings. The performances of EMPSMC
and MPPIC are compared and analyzed with and without disturbance. The results show that the
system’s settling time is minimized by introducing SMC, and the overshoot is also reduced. Moreover, it also provided better steady-state stability. Similarly, dynamic improvements are achieved
with EMPSMC for tracking the desired dc reference voltage demand. The simulation results validate
the performance of the designed model.
